Stress and Gut Bacteria

In a recent commentary paper that was published in GUT journal, the details of the changes in bacteria behavior with human stress hormones were explained. There are several pieces of evidence that bacteria change their virulence (attacking properties) when they sense human stress hormones such as Norepinephrin. This may open a new avenue in the investigation of the role of stress on GI tract and explain why the population of bacteria may differ in those patients with IBS. GUT2007-10-10 12:29:02
